Filed: 1938-08-08
Abstract: 517,871. Rolling tubes and rods ; making cased forms. GERBRACHT, E. Aug. 8, 1938, No. 23397. [Classes 83 (ii) and 83 (iv)] Malleable steel is formed direct from molten metal by allowing the metal to fall into a funnel formed by the spherical surfaces of 3 or more rotating rolls which form a pass. In falling, the metal falls or is sprayed, Fig. 7, on the cooled surface so that it breaks up into small drops which weld together in the funnel and are rolled out into, e.g., square or rectangular section or by grooving the rolls, e.g., as in Figs. 14, 15 the, section may be circular, hexagonal &c. Fig. 9 shows an individual roll cooled by fluid blocked at i in the hollow shaft so that it has to flow through conduits k to the interior and out again, the exit being smaller than the inlet to make sure that the roll is filled. Fig. 10 shows spherical surface rolls with cylindrical extensions o forming a pass. The molten metal may form a continuous tube by means of a core, e.g., in Fig. 17 or in shorter tube lengths by a core supported from below, or may encase a copper, aluminium, steel &c. core rod, Fig. 19, or may encase a tubular rod, Fig. 20.

Filed: 1934-08-22
Abstract: 443,424. Thermostatically and clockwork actuated valves. WALKER, C. BELL-, 38, South Bar, Banbury, Oxfordshire, and SMITH & SONS (MOTOR ACCESSORIES), Ltd., Cricklewood, London. Aug. 22, 1934, No. 24230. [Class 135] A regulating valve for a gas cooker comprises a valve member 15 controlling the passage of gas from an inlet chamber 11 to an outlet chamber 12 to the burner, the position of this valve being regulated by a bi-metallic thermal element 20, subjected to the heat from the burner, through a rod 22 screwed into a reciprocating sleeve member 29 which abuts against a sleeve 16 carrying the valve 15. The chambers 11, 12 are sealed by flexible diaphragms 18, 19 and the spring 23 tends to keep the valve sleeve 16 in contact with the sleeve 29. The initial position of the valve is adjusted by rotation of an indicating head 28 which by means of a splined portion 33 of the spindle 22 rotates the spindle and adjusts its axial position and therefore that of the valve with respect to the sleeve 29. A clockwork mechanism is provided for closing the valve 15 after a predetermined interval of time has elapsed and comprises a spring 40 which is wound up the requisite amount corresponding to the predetermined interval of time by a knob 45 which is normally clutched by a clutch 46 to the spindle 48. To wind up the spring and so set the timing mechanism the knob 45 is pulled outward to disengage a pin 57 from a hole 60 in the plate 41 and also the clutch 46, and turned so that the sleeve 43 winds the spring 40. The knob is then released and the clutch 46 engaged, the pin 57 riding on the top of the surface 41. The clockwork operates through an escapement mechanism 51, 52, 54 until the pin 57 drops into the hole 60 and the spindle 48 is moved axially by axial pressure from the spring 40 to close the valve 15 through the lever 61. When the time -control mechanism is not required, the control knob is turned to its fullest extent so that the pin 57 is held against a stop 58. In a modification, Fig. 5, a cam 68 is arranged on an extension of the spindle 48 and through a follower-lever 73, carrying a toothed quadrant 70, actuates a gear 69 arranged on the rod 22 to automatically vary the position of the valve and therefore the temperature of the oven during the period of operation according to the predetermined contour of this cam. Specification 419,378 is referred to.
